THESE TUBES WOULD PROBABLY BE GREAT FOR HEAVY TRAIL RIDING OR DUAL SLALOM. I GOT A PAIR A MONTH AGO AND USED THEM FOR DOWNHILL AND AGGRESIVE TRAIL RIDING AND THEY FLATED ON ME ABOUT 4 TIMES. (ALL OF THEM WERE SNAKE BITES) SO THATS LIKE 8 HOLES. GO WITH INTENSE, KENDA OR A HEAVIER TUBE FOR AGRESSIVE RIDING.
